Low Concentration Formaldehyde

Activated carbon fibers supported TiO2 nanoparticle photocatalyst was prepared by immersing activated carbon fibers in water suspended with TiO2 nanoparticles under sonication. X-ray diffraction and scanning electron microscopy were applied to characterize the crystallinity and morphology of the photocatalyst. The photocatalytic activity of the prepared photocatalyst was evaluated by the photodegradation of formaldehyde for indoor air purification. The result showed that the low-concentration formaldehyde in the polluted indoor air could be photocatalytically degraded over the prepared photocatalyst, with the formaldehyde concentration in the product air falling into the standard range that is specified by the Chinese Indoor Quality Standard.

Dandelion-likeγ-manganese dioxide (γ-MnO2) nanofibre/activated carbon microbeads (ACMBs) composite is prepared by an in situ coating technique. The structure and morphology of the composite are characterized by scanning electron microscopy and X-ray diffraction. The results show thatγ-MnO2nanofibre is uniformly encapsulated on the surface of ACMB, and the composite finally becomes a dandelion-like microbead. Cyclic voltammetry, galvanostatic current charge/discharge, and cycle life measurements are used to evaluate the electrochemical behaviors of the composite. Since the composite is able to undergo pseudofaradic charge transfer reactions and hereto contributes together with the double-layer effect to the total capacitance of the material, the specific capacitance of the composite is as high as 375.9 F g-1at a scan rate of 1 mV s-1, which is significantly higher than the pure ACMB. Besides, the capacitance retention of the supercapacitor using the composite as electrode-active material keeps still 93% after 1000 cycles.

The method for determination of sizes and structural characteristics of nanographites in activated carbon fibers (ACFs) by analyzing their experimental X-ray diffraction profiles has been developed in the paper. It uses the curves of X‑ray scattering calculated for the set of nanographites consisting of benzene- and phenalene-bazed nanographenes of various sizes, which interatomic and interlayer distances depend on the number of atoms in layer. The developed method can be also applied to analysis of the X-ray diffraction profiles of other nanocrystalline graphite structures. The data acquired by the method agree with results of Raman spectroscopy and small-angle X-ray scattering on ACFs structure motives.
